Y i I i In the construction shown in Fig, 5, 91 represents the engine cylinder and '92 its head, 93 being the 'usual' intake port, which is controlled by a valve 94 arranged to seat on the casing 95. The valve 94 is provided with a stem 97 and is normally maintain-ed upon its seat by the spring or resilient mom-,- ber 99, cotiperating with the collar 100 and the casing. 101 is a collar similar to those previously described for limiting the-movement of the valve, At the intake port, within the cylinder, may be provided the mixer 102, having openings 103 theret'hrougln Arranged in the cylinder wall, or in the head, as shown in the head,;is provided a port 104;, normally controlled by'a valve 105,- which is arranged to cotiperate with a suitable seat on the casing 106. The valve is provided with a stem-105, normally maint-ained"'ii'pon it's seat by a resilient member collar 110 and the yoke 108 on the casing, 111 being a collar thatscrves as a stop, as heretofore described in the other construct-ions.- The operation of this device is as follows: The mixture is in the casing, and thence passes through the chamber '90 therein past the valve 9%, and out through the openings 103, being. thoroughly mixed by the mixer. At the same time'it is met by an opposing current of ai.r entering the valve 105, which mixes in with the mixture.

l-laving-thus described my is obvious that various immaterial modilications may be made in the same withoutdeparting from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form, construction or combination of parts herein shown and described, or uses mentioned.

ll hat. I claim as new and desire to secure by Letters Patent is i 1. The, combination in an internal combustion engine of a cylinder, provided with an intake port, and auxiliary means for admitting air to the interior of, the cylinder simultaneously with theadniission of the charge therein, and a mixing cylinder within the engine cylinder and overlying said intake port.

2. in an internal combustion engine, provided with a cylinder having an intake port. the combination of means for admitting air to the interior of the cylinder prior to the mixture through said port tron, chamber, means carried thereby for tinder through said 5. In an internal combustion engine,

4. In ,an internal combustion engine, a cylinder" provided with an intake ort means for controlling theadmis'sion 'o the to the combuscontirollin'g the admission of air to the cyl-j port simultaneously with the admission of the charge therein, and a mixer secured to the inner the combination of means for controlling the passage of a mixture through the intake port, means for wntro'lling the admission of air tl'ierethrough, an apertured mixing cylinder within the engine cylinder and a spreader in the mixing cylinder. 6. In an internal combustion engineprovided with an intake-port, the combination 'of means for controlling the passage of the mixture through said port, auxiliary means cooperating therewith for controlling the admission of air through said port, and a mixer within the cylinder adjacent said port.

7. In an internal combustion engine, the combination of a cylinder provided with an intake port, a valve for. controlling said port, a valve mntrolling the admission of air-through said port, and a mixing member overlnng both of said valves.

S. In an internal combustion engine, the combination of a cylinder provided with for said port, an auxiliarv valve cotiperating therewith for controlling the admission of air through said port, and a disk shaped member overlying both valves and having ,an apertured side wall. "ILJn a device of the kind described, a. cylinder provided with an intake port, .a mixer arranged-within the c \-'lindci', a valve for controlling the fluid passing through said mixer through said port, and means for supplying the air to said mixer simultaneously with the passage of themixture therelhrough.

10. In adevice of the kind described and in combination, a cylinder providtd with an intake port, a mixer arranged within the cylinder at said port, a controlling valve for said port, and means for admitting air the engine cylinder in the 4 wall of tlie cylinder and overlying said poll.
